73A-270 Arbitrary Pulse/Pattern Generator Module
Prerequisites
The test sequences in this procedure are a valid verification of the 73A-270 when
the following requirements are met:
H The 73A-270 has been calibrated within the last 12 months
H The 73A-270 module covers are in place and the module is installed in an
approved VXIbus mainframe according to the procedure in Section 2 of the
Operating Manual
H The 73A-270 has passed its power-on self test
H The 73A-270 is operating in an ambient environment as specified in
Section 1 of the Operating Manual and has been operating for a warm-up
period of at least 10 minutes
Equipment Required
This procedure uses traceable signal sources and measurement instruments.
Table A–1 lists the required equipment. You may use equipment other than the
recommended examples if it meets the minimum requirements listed.
